LAST WEEK, Scarborough and his "Morning Joe" co-host, Mika Brzezinski, visited the Republican presidential nominee at Trump Tower to rekindle a once-rosy relationship that has turned bitter and adversarial, sources with knowledge of the meeting told CNNMoney.

The three also discussed the possibility of conducting an interview for "Morning Joe," though nothing was decided or finalized, one of the sources said. Scarborough did not respond to a request for comment.

The meeting, which NBC and the Trump campaign both declined to comment on, comes after a summer of barbs and insults.

Trump has repeatedly slammed Scarborough and Brzezinski on Twitter and even spread a rumor that the two were romantically involved.

Meanwhile, Scarborough and Brzezinski have been increasingly outspoken in their criticisms of Trump. Just three weeks ago, Scarborough released a song and music video he made in which he mocked Trump as "a soft and flaccid man" with "tiny little hands" and referred to him as "Amnesty Don," a nickname he'd given Trump earlier.

The need for any rapprochement is surprising, given how close Scarborough and Trump used to be. Throughout the Republican primaries, Scarborough was one of Trump's biggest media boosters. He praised and defended him on the show, offered campaign and debate advice in private, and even refused to rule out the idea of one day being Trump's running mate.

"You guys have been supporters, and I really appreciate it," Trump told the co-hosts after he won the New Hampshire primary. "Not necessarily supporters, but at least believers."

While Scarborough's support for Trump was a source of concern for his colleagues at NBC News and MSNBC -- sources at the time described it as "over the top" and "unseemly" -- the host frequently denied any favoritism.

You find out what someone is really like in "battle," and Olbermann is who you want to be in a foxhole with, Patrick said. "On the air, we had each others' backs," said Olbermann.-David Goetzl: "Keith Olbermann, Dan Patrick still brothers long after ESPN's 'Big Show'"; MediaPost blog, 4-6-2012

Mika was seen entering Trump Tower yesterday. I'm not sure whether Joe has been in touch.

Wouldn't it be great if Joe went to work for the Trump administration, and someone else took over MSNBC mornings?
